Description Timo Aaltonen 2012-09-26 05:29:41 UTC

downstream bug from ubuntu:

https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/927168

started happening for more people when the default fallback session started using llvmpipe. Applies to 8.0.x and 9.0.

It's worked around for now ("Check that pixmaps which aren't managed by us actually exist before binding") but a proper fix should be added to mesa.

IIUC the compiz-core patch

  https://i116412274.restricted.launchpadlibrarian.net/116412274/2c4b2354-00dc-11e2-a4a9-002481e91f22.txt?token=60HdnFNMGFc5zJXJwfwH9pN2wg6pmXxn

the fix consisted of not calling glXBindTexImageEXT when 

      XGetGeometry (dpy, pixmap, ...)

returns false.


https://www.opengl.org/registry/specs/EXT/texture_from_pixmap.txt does say that 

  "Currently, only pixmaps can be bound to textures.  If <draw> is not a
  valid GLXPixmap, then a GLXBadPixmap error is generated."

so indeed this should be handled better.

This technically is a bug in st/dri though.
